Nextrade Dominates South Korea’s $2.4 Trillion Stock Market with 30% Share Grab

Korean trading platform Nextrade just pulled off what traditional brokers only dream about—capturing nearly a third of the country's massive stock market.

The $2.4 Trillion Takeover

Nextrade's 30% market share isn't just impressive—it's a seismic shift in how Korea trades. While legacy institutions were busy with paperwork, Nextrade built a platform that actually works for modern investors.

Traditional Finance's Wake-Up Call

That 30% slice represents billions in daily trading volume moving through Nextrade's systems. The platform's growth trajectory makes Wall Street's incremental gains look like amateur hour.

Korean Markets Transformed

With nearly one in every three Korean stock trades now happening on Nextrade, the platform has become the default choice for a generation that prefers clicks over phone calls.

Maybe traditional brokers should've spent less time on golf courses and more time building functional technology—just a thought from the digital revolution that's eating their lunch.

Retail traders move to Nextrade en masse for speed and flexibility

The shift has been powered by South Korea’s retail army, often called “ants.” These small traders make up 86% of Nextrade’s activity, pouring cash into crypto, Magnificent Seven stocks, and even Leveraged U.S. ETFs. They want speed, longer hours, and cheap fees; and Nextrade apparently delivers.

Here’s the kicker: transaction fees are 20–40% cheaper than KRX. You also get more price-setting options. If you don’t tell your broker which platform to use, it auto-selects the one offering the better deal. This price-based system has helped Nextrade grab order FLOW quickly.

Nextrade doesn’t support IPOs, but that hasn’t stopped it from exploding in popularity. Foreign investor participation is also climbing, up to 11% from basically zero at launch. Domestic institutions, though, are still mostly sitting out. Korean media blame “system stability worries,” though Nextrade hasn’t had any major outages.

As Nextrade grows, KRX is feeling the pressure. Regulators have been caught flat-footed. They rushed to review rules that cap alternative trading systems (ATS). The Financial Services Commission (FSC) was forced to temporarily lift the 30% single-stock volume cap in September after 500 stocks broke the limit.

If they hadn’t, Nextrade would’ve had to freeze trading on a ton of names. “It WOULD become impossible for investors to trade during their commute to office,” the FSC said in a public statement.

Regulators cap Nextrade’s growth while Seoul pushes U.S. tariff deal

But the 15% overall market volume cap still stands. To stay under that line, Nextrade suspended nearly 150 stocks in August and September. That’s why the platform’s market share by volume is smaller than by value.

Compare that to the U.S., where 80+ ATS platforms handle just 20% of market value, or Japan, where three ATS players split just 10%. Nextrade’s growth is reportedly on another level.

“It’s unprecedented globally,” said Kang Sohyun, senior research fellow at the Korea Capital Market Institute. “If you look at other similar markets with one large exchange and smaller bourses, such as Australia and Japan, Nextrade’s expansion has been very rapid.”

The legal foundation for Nextrade was laid way back in 2013, part of South Korea’s plan to modernize its capital markets. But things stalled until 2023, when Nextrade got preliminary approval. Its CEO, Kim Haksoo, used to be a financial regulator himself.

Meanwhile, South Korea’s broader economic strategy is shifting fast. Presidential policy chief Kim Yong-beom said Sunday the country had made “substantial progress” in tariff talks with the United States.

Kim, alongside Seoul’s industry minister and other officials, met U.S. negotiators in Washington last week. At stake is a $350 billion investment fund, key to a deal that capped U.S. tariffs on Korean goods at 15%.

That same weekend, top Korean tycoons, from Hyundai Motor, SK Inc., and Hanwha, played golf for over seven hours with Donald TRUMP at Mar-a-Lago. Executives from Japan and Taiwan also joined, according to Yonhap and other local media. Trade and investment likely came up.

Trump, who often mixes business with golf, has used the Florida estate for dealmaking with global power players. And with the Asia-Pacific Economic Cooperation summit around the corner, Kim said the odds of finalizing a trade deal have now “increased.”
